This is one hour each of LRGB (in each filter) with Takahashi FSQ85 telescope and Atik 460 CCD camera with Baader LRGB filters. I did not use Ha filter on this image. The data was collected on 29th November 2013 and it was the second light of the telescope (first light being The Double Cluster here).
M33 at 3 million light years is the most distant object that can be viewed by the unaided eye and is visible in a very dark sky as a very tenuous patch if light. It has very low surface brightness, it lacks a very bright core and tis makes it quite hard for beginners to see in their telescopes since they expect to see something much brighter and colourful.
The two above images show an annotated and an inverted version of the galaxy.
